Zip 2.3 works correctly:
$ (umask 0; zip test.zip feedlist.opml; ls -l test.zip; rm test.zip)
  adding: feedlist.opml (deflated 80%)
-rw-rw-rw-    1 lupe     lupe         3156 Aug  4 10:52 test.zip
$ (umask 077; zip test.zip feedlist.opml; ls -l test.zip; rm test.zip)
  adding: feedlist.opml (deflated 80%)
-rw-------    1 lupe     lupe         3156 Aug  4 10:52 test.zip

HTH,
